Ring PCB---- Industrial 3D Printer PCB assembly Project Case
 
This case documents Ring PCB's collaboration in providing full-turnkey PCBA services for a well-known UK-based industrial 3D printer manufacturer (confidential under NDA), demonstrating end-to-end capabilities from requirement alignment and solution design to delivery.
 
I. Basic Project Information
Project Dimension Details 
Service Scope Full-turnkey PCB Assembly (PCBA) service, covering component sourcing, SMT, testing, and packaging 
Quantity 12,000 units 
Export Country United Kingdom 
Client A well-known industrial 3D printer manufacturer (confidential by NDA) 
 
II. Client’s Core Requirements
 
The UK client approached Ring PCB seeking a trusted, scalable PCBA partner to provide controller boards for their next-gen industrial 3D printers, with the following requirements:
 
1. Hardware Design: Compact multilayer PCB with fine-pitch components to fit custom structures; embedded stepper motor drivers, temperature sensors, and communication interfaces.
2. Performance Requirements: Stable performance under continuous high-current loads for 24/7 operation; EMC-compliant layout to meet UK/EU regulations.
3. Delivery & Service: Fast turnaround for prototyping and verification, followed by rapid mass production; full-turnkey services including component sourcing, SMT, testing, and packaging.
 
III. Ring PCB’s Solution
 
To meet the client’s needs, Ring PCB’s engineering team proposed and implemented a comprehensive PCBA solution, with key measures as follows:

 PCB Design: 6-layer PCB design with impedance-controlled routing; high-TG and low-EMI substrate materials selected for complex industrial environments.
 Function Integration: Integration of STM32 MCU, stepper driver ICs, and CAN/UART ports to meet the core control needs of 3D printers.
Manufacturing Process: Precision SMT assembly combined with DIP (Through-Hole Technology), supporting fine-pitch soldering of BGA and QFN packages to ensure component soldering reliability.
Quality Control: Every board undergoes Automated Optical Inspection (AOI) and functional testing; batch serialization and traceability are enabled for full quality accountability.
Environmental Adaptation: Conformal coating applied to all boards to enhance humidity and corrosion resistance, suitable for long-term industrial use.

 
IV. Production & Delivery
 
1. Prototyping Phase: Rapid prototyping and verification completed in 5 working days, efficiently meeting the client’s pre-production testing needs.
2. Mass Production Delivery: Full production of 12,000 units was completed in 3 rolling batches over 7 weeks, with smooth export to the United Kingdom.
3. Packaging & Logistics: All boards were shipped with anti-static (ESD) protection packaging to ensure product safety during transportation, supporting global export logistics.
 
V. Client Feedback
 
Quote from the Engineering Director of the UK client: “Ring PCB’s professionalism and speed truly impressed us. Their engineering support and manufacturing consistency gave us the confidence to scale production. We consider them a long-term PCBA partner.”
